Limiting white balance in my raw images

Submitted by ronald_d on

Hi there,

I found out about libraw while looking for a solution with my raw images, that are messed up by my DSLR...
Part of the image has the white balance set too high.
Is there already someone who wrote an application to limit the white balance to a certain maximum value?
Otherwise, where in this software can I do this myself and store the updated raw image under a new name?

Thanks a lot for all the feed back :-)

Regards, Ronald.

It is unclear how do you mean

It is unclear how do you mean saying "white balance set too high". Could you please upload a sample raw and provide a link to it, to better understand the issue?

Dear Sir:

There is no problem with white balance on the image. Possibly you mean that the shot contains blown-out areas, but I can't say how much of those can be brought back as the image you've uploaded is in fact JPEG, not raw PEF.

Hi Iliah,

I have created a jpg from my raw file, if needed I can also share the raw file. The fact is that for all raw images from a certain day, this effect is present in the same are (left-hand side of each picture). Or is it then the intensity that I need to reduce for the raw image?

Regards, Ronald.

Dear Sir:

There is certain amount of flare, and possibly the exposure was too much, but I can't say for sure without the raw. You can download free trial of our RawDigger and check the exposure yourself of course: https://www.rawdigger.com/download

Hi Iliah,

Rawdigger gave me new insight :-)

I open one of my images in rawdigger and noticed that the min and max values for the colours are really different:
(values are min max avg and sigma)
R 2 2521 307 446
G 8 4045 716 1004
B 1 4046 683 1038
G2 5 4045 716 1004
This pef file can be found here:

Is there anything I can do to correct this image (and about 50 other images I have with similar problem)? There are some wedding pictures among them and I'd like to get these fixed...

Regards, Ronald.
